A nurse is educating a client about the inheritance pattern of cystic fibrosis (CF). What information should the nurse provide regarding the likelihood of a child developing CF if both parents are carriers?

"If both parents are carriers, there is a 50% chance that their child will have CF."

"If both parents are carriers, their child is guaranteed to have CF."

"If both parents are carriers, their child will be a carrier but will not have CF."

"If both parents are carriers, their child will have a 25% chance of having CF."

Answer and Explanation

The Correct Answer is D

A) Incorrect. If both parents are carriers, their child's risk of having CF is 25%, not 50%.

B) Incorrect. While the risk is increased, having two carrier parents does not guarantee that a child will have CF.

C) Incorrect. If both parents are carriers, their child can inherit two normal genes (no CF), one normal and one CF gene (carrier status), or two CF genes (CF).

D) Correct. When both parents are carriers, there is a 25% chance that their child will inherit two CF genes and have CF, a 50% chance of being a carrier, and a 25% chance of inheriting two normal genes (no CF).
